Hyesung himself asked Lim Chang Jung to participate in the song because Lim Chang Jung was a singer he respected. Hyesung's label said, "Next year, Hyesung will hit his 10-year anniversary for his solo debut. He was honored for the meaningful collaboration for the remake project with Lim Chang Jung, a sunbae he always respected. We thank Lim Chang Jung once again for participating in the remake project. Fans will be able to hear a new charm from this new 'Doll', so please show Hyesung and Lim Chang Jung a lot of support."
